Open redirect via unvalidated confirmation destination
Published Sep 15, 2026 · Updated Sep 15, 2026
Open redirect in Kiwi TCMS 16.0 and earlier allows remote attackers to redirect users to external domains through account confirmation links. The account confirmation endpoint uses its unvalidated next parameter directly as the redirect destination, including arbitrary external URLs. Exploitation requires a victim to follow a crafted link on a trusted Kiwi TCMS host, enabling credential harvesting or malware delivery.
